Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of detailed description of the invention.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or part, and do not get rid of other element or other part.
As shown in Figure 1, comprise the following steps according to the water-free detection method of the electronic refrigeration water dispenser quality of the specific embodiment of the invention:
Step 1, utilizes the NTC resistance of digital display thermometer and electric bridge detected electrons ice courage assembly;
Testing process as shown in Figure 2, digital display thermometer probe 4 is inserted in electronic refrigerating container, record the temperature in electronic refrigerating container, bring in and detect its resistance with two of the NTC resistance 3 in electric bridge 1 connecting electronic ice courage assembly again, then contrast the R-T table of comparisons, judge NTC whether qualified (meeting the scope of the table of comparisons for qualified).Wherein, NTC resistance is thermistor, and along with variations in temperature, resistance is also along with variation.R-T table is the corresponding table of the resistance of NTC resistance under corresponding temperature.The startup of NTC resistance control electronic refrigerating container with close.
Wherein, as shown in Figure 3, the electronic refrigerating container of electronic refrigeration water dispenser comprises: Switching Power Supply plate 21, fin 20, refrigerating chip 22 and fan 23.The course of work of electronic refrigerating container: complete machine input power 220v is to Switching Power Supply plate, the direct current of Switching Power Supply plate output 12V is to electronic refrigerating container refrigerating chip, make refrigerating chip work, fin is close to the heating end of refrigerating chip, fan is facing to fin blowing, make refrigerating chip heat end distribute heat, heat absorbing end continues to absorb heat, thereby reaches refrigeration object.When the temperature in electronic refrigerating container reaches 12-15 degree, NTC resistance senses, gives resistance signal of a Switching Power Supply plate, the action of Switching Power Supply plate, stop to refrigerating chip and fan power supply, electronic refrigerating container quits work, and when temperature inside is higher than 15 degree, NTC resistance senses, give Switching Power Supply partitioned signal, the action of Switching Power Supply plate, refrigerating chip and fan are started working, so circulation.
The most common failure of electronic refrigerating container comprises: 1, when refrigerating chip direction is anti-loaded, and heating end and heat absorbing end exchange, now the power of detected electrons ice courage is normal, but becomes heat by refrigeration, is difficult to find.2, NTC resistance is abnormal, and short circuit, rosin joint, resistance do not meet the R-T table of comparisons, and NTC gives wrong signal, and electronic refrigerating container cisco unity malfunction, causes normally startup-shutdown of electronic refrigerating container, and cryogenic temperature point does not reach requirement.3, Switching Power Supply plate output 12V direct current, both positive and negative polarity connects instead, and former heating end changeable heat-absorbing, former heat absorbing end become heat release, and now the power of detected electrons ice courage is normal, but becomes heat by refrigeration, is difficult to find.
Step 2, utilizes the air-tightness of air-leakage detector detected electrons refrigerating drinker internal duct;
Need the internal duct of the electronic refrigeration water dispenser detecting to comprise: muffler 6, tap 7, hot single delivery port 8, hot courage 9, inner silica gel part pipeline 13, electronic refrigerating container 15, electronic refrigerating container delivery port 14, electronic refrigerating container discharge outlet 17 and hot courage discharge outlet 18.Testing process as shown in Figure 4, air-tightness is detected to the top cover 11 (it is 12 with the contact point of top cover 11 that air-tightness detects fixture 10) that fixture 10 inserts electronic refrigeration water dispenser, and good seal, and block muffler 6, then start air-leakage detector 5, carry out qi of chong channel ascending adversely toward machine intimate, make the air pressure in cavity volume arrive appointment air pressure 70kpa, inflationtime 4s, then carry out pressurize 10s, make the air pressure in cavity volume even, finish rear detected pressures 2s, when the amount of leakage of air pressure is less than 100pa for sealing is qualified.
Step 3, utilizes comprehensive tester to carry out electric-examination to electronic refrigeration water dispenser;
Water dispenser is to electric-examination post, automatically detect with comprehensive tester: water dispenser socket is plugged comprehensive tester, program starts, open cooling and warming switch, check whether indicator lamp normally lights, after indicator lamp normally lights, the first step, beat ground connection 1s (test complete machine whether normal ground connection), drop bar is placed on the device seat farthest of disembarking, and comprehensive tester detects automatically, and qualified green light enters next step automatically; Second step, beat withstand voltage 2s (whether test complete machine exists high-pressure situations, ensures handling safety), input voltage becomes 1800V and continues 2s, automatically detects, and qualifiedly enters next step; (ensureing complete machine insulating properties) leaked in the 3rd step, survey, the automatic leakage current 5s that surveys after starting, and green light is qualified enters next step; The heating power 2s of the 4th step, calorimetric courage, turns off refrigeration switch, detection power 2s automatically, and green light is qualified enters next step; The refrigeration work consumption 8s of the 5th step, survey electronic refrigerating container, turns off and heats switch, opens refrigeration switch, automatically detection power 8s.Five detections are all by being qualified.(comprehensive tester program: ground connection 1s-is withstand voltage, and 2s-leaks 5s-heating power 2s-refrigeration work consumption 8s)
Step 4, utilizes the temperature rise of infrared thermometer detected electrons ice courage fin;
Testing process as shown in Figure 5, water dispenser is to inspection post, plug in, open refrigeration switch, start refrigeration system, make electronic refrigerating container work, aim at electronic refrigerating container fin 20 with infrared thermometer 19, observe digital display screen, it is qualified that heatsink temperature continues to rise in 8s, if continuous decrease is defective, for example the electrode of Switching Power Supply plate is anti-loaded.
By the detection of this four step, ensure that sealing and the whole Circuits System of water dispenser normally worked.Electronic refrigeration water dispenser production line can be saved operating personnel 3 people, and every machine is saved test electricity consumption 0.5 and spent, and saves test water 3L, realizes cleaner production.
To sum up, the water-free detection method of this electronic refrigeration water dispenser quality is by adopting the equipment such as air-leakage detector, electric bridge, temperature digital display device, infrared thermometer, in the situation that not adding water running, detect, ensure the working properly of the sealing of water dispenser internal duct and electrical equipment vigour part, reduce the waste of power and water energy, improve detection efficiency, made the environmental protection more of whole testing process, realize cleaner production.
The aforementioned description to concrete exemplary of the present invention is in order to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.Exemplary embodiment is selected and the object described is to explain certain principles of the present invention and practical application thereof, thereby made those skilled in the art can realize and utilize various exemplary of the present invention and various selection and change.Scope of the present invention is intended to be limited by claims and equivalents thereof.
